22045 Pressure Controllers, Indicators, and Recorders
The Charlotte Area Transit System (CATS) Bus Operations Division (BOD) anticipates contracting out the purchase of a Tire Pressure Monitoring System (TPMS) for its fixed route and paratransit system. The TPMS shall be easy to use and provide accurate data. CATS has over 1,900 tires in its fleet. The contractor would be responsible for the execution of the project including, but not limited to, installation and training.

Charlotte Water manages an extensive water distribution network throughout Mecklenburg County NC. Monitoring the pressure within this system remotely is crucial for ensuring its optimal performance. Charlotte Water is seeking to upgrade to smart hydrants. The new smart hydrants must maintain Charlotte Water’s current monitoring and reporting capabilities, including remote pressure reporting, historical data access, pressure zone grouping, and a web-based interface. Additionally, they must function even when the hydrant is off and provide reliable pressure readings throughout the year, including during freezing temperatures.
Charlotte Water is seeking a contract with a company to provide smart hydrants. Charlotte Water is testing multiple solutions to measure system pressure throughout the water network. The solutions utilize “smart hydrants” that take pressure measurements at pre-defined intervals and store the information to a cloud-based application. The selected solution will be used to replace the existing monitors currently in use. The existing monitors are attached to hydrants and require the hydrants to be charged. They are also removed during the winter months and reinstalled in the spring. The new “smart hydrants” will not need to be removed/installed every year and do not need the hydrant to be manually opened to record pressure readings. The new solution will stream-line the process for Charlotte Water and allow for more frequent/timely measurements.
